Our Water System

MAWSS drinking water meets and often exceeds all federal and state standards for safety. 

Our two water treatment facilities have been recognized as Optimized Plants by the Alabama Department of Environmental Management or ADEM, meaning they consistently maintain treatment standards that are over and above those required by the U.S. Environmental Protection Agency (EPA) and ADEM, providing an extra level of protection for public health.
